文/South
Liu Shulin，A very famous name in the field of mathematical economics w88。He has been a visiting professor at the Business School of City University of Hong Kong for many years、PhD in w88 and Management Science and Engineering，Yu2002Comed to our school in 1977 as the director of the Department of Quantitative Economics at the School of International Economics and Trade，Professor and doctoral supervisor；2006As the assistant to the dean, he assisted Dean Zhao Zhongxiu in carrying out postgraduate training work。
For several years,Liu ShulinProfessors while undertaking teaching tasks，Put w88 field on mathematical economics、International bidding and auction theory、Game theory and multi-criteria decision-making theory and their applications in the fields of economy, trade and finance，And publish papers in this field30Multiple articles, obtained2001YearNationally OutstandingDoctoral Thesis Award and the Second Prize of the Ministry of Education’s Scientific and Technological Progress Award, etc.。Liu Shulin has chaired several national-level natural science research projects，Ministry of Education Humanities and Social Sciences“Eleventh Five-Year Plan”Planning projects and key course construction teaching projects of the school’s graduate department。He is outstanding in scientific w88 and teaching work2005Became the Ministry of Education“New Century Excellent Talent Support Plan”Selected, and in2004, he won the title of Beijing Outstanding Teacher.
Expand w88 and application in quantitative economy
Professor Liu Shulin’s research field is the application of mathematical economics methods，His w88 casino gamescurrent research interests focus on utilizing game theory、Optimization theory、Research on differential equations and probability theory, bidding and auction theory。The research method of mathematical economics can be roughly described as (1) Through literature or observation and experience of real economic phenomena，Draw some realistic economic assumptions and some economic conclusions，That is, what is known？What to do？。This step is very important，Also very difficult。（2) How to draw these economic conclusions，How to do it？We must use mathematical symbols、Mathematical functions、Mathematical inequality、Mathematical equations, etc. to express or describe these economic assumptions and economic conclusions，That’s it(1) The observation and experience of literature or real economic phenomena are expressed as a mathematical proposition or a mathematical model。The remaining work is to use relevant mathematical knowledge to reason；Export using mathematical symbols、Mathematical functions、Mathematical inequality、Conclusions expressed by mathematical equations, etc.；Some new conclusions may also be drawn in this process。
Another way to study quantitative economics is to start with just some assumptions，Also roughly know what to do，But I don’t know what the conclusion is？At this time，Just try to use these assumptions for mathematical modeling，Solve this model，Let’s see if we can draw some conclusions that are consistent with economic phenomena，Or after reaching the conclusion，Trying to find more consistent economic phenomena。No matter what kind of w88 process or method，Assumptions and models may need to be continuously adjusted during the w88 process，Until a conclusion is drawn that is consistent with an economic phenomenon。
Currently，The bidding w88 casino games loginand auction theory studied by Professor Liu Shulin，Results obtained using decision science and quantitative economics research methods，Although most of them are still at the theoretical level，But a small number of research results such as the results of "multi-attribute decision-making methods and data envelopment analysis"，is being applied to their work practice through the on-the-job graduate students he leads，For example, the bidding of State Grid Corporation of China、Bid evaluation in progress。Also，This result is also expected to be applied to bidding and bid evaluation practices in the Beijing construction market。
The greatest wish of theoretical researchers is to put w88 results into practice。But as a scholar，Professor Liu has a lot of w88 work to do，Speaking of combining theory with practice，Easier said than done，There is great difficulty here。一来，You must have time to investigate and visit the actual department，二来，To obtain support from the actual department or obtain its real data，This is even more difficult，三来，Whether a cooperative w88 relationship can be established depends on whether both parties can reach a consensus。Of course，Time is never enough for scholars，For them, not being able to do anything at all is the most difficult problem。
Professor Liu Shulin has established a good cooperative relationship with Zhongdu International Auction Co., Ltd. and the R&D Department of Beijing Construction Market Contracting and Trading Center，The two projects are currently progressing smoothly。Professor Liu thinks，Carry out cooperative research with enterprises，Is the best way to apply theory to practice。Some of his scientific research results came in handy when filling out the application forms for doctoral programs in our school，This is w88 online casinoboth a gain and a great comfort to him。
Scientific w88 must be patient and not afraid of hardships
Professor Liu Shulin is doing postdoctoral research、Have done many scientific research projects after working at City University of Hong Kong Business School and our school，Especially in our school5During the year, he presided over as many scientific w88 projects9item。so far，He has presided over and completed two National Natural Science Foundation projects，After two project evaluations，One is excellent，The other one is Liang；He also chaired a China Postdoctoral Fund project；is hosting a National Natural Science Foundation of China project and a2005"New Century Excellent Talent Support Plan" project of the Ministry of Education.
Professor Liu Shulin’s success rate in applying for scientific research projects is not low。He thinks，It is important to correctly understand the application for scientific research projects，From a general perspective，The successful application of the project is for the scientific research development of the school，A small contribution to the transformation of the school into a research university；From a young age, whether you have research interest is the most important thing。These two items are the motivation for success in applying for scientific research projects。Of course, whether the application can be successful depends on many factors，But the most important factor，That is, factors that you can control，It means there is preliminary preparation and accumulation，This includes the publication and topic selection of a certain number of academic papers of high quality。Filling in the application form cannot be ignored。The publication of a certain number of academic papers of high quality，requires researchers to have a lot of patience，It takes hard work；On the choice of topic，The topic may not be a hot research topic in today’s academic w88 online casinocircles，But you must have your own opinions and opinions in research。
In research，Professor Liu Shulin has indeed put in a lot of hard work。40before years，His solution to running out of time is，Extended working hours、Reduce rest time，No rest during holidays。He basically does it in the early morning every day1Go to sleep.40After 22151_221711Rest after clicking，But most of the time，He arranges his bedtime to be close to midnight12Points。Even during the few years of working in Hong Kong，The same is true for Liu Shulin，In his busy schedule，He rarely leaves school，Commute to and from get off work every day at the school residence between 2:00 and 1:00 a.m.；Even during the six months of high-ranking visits to the United States，He has hardly played any games。
Professor Liu who keeps climbing on the road of scientific w88，Also expressed his views on the scientific w88 project establishment activities for undergraduates，He believes that undergraduate scientific w88 activities should be diverse，Students can practice the theoretical knowledge they have learned through scientific w88 activities，Problems encountered in practice should be actively discussed and communicated with the teacher，Improving knowledge and analytical skills。
Finally, best wishesLiu ShulinProfessor in Mathematical Economics、Multi-criteria decision-making、Achieve greater achievements in w88 fields such as project decision-making。
